c10e6bcbed Attempting to insert a value of 'now' into a datetime type
results in a bogus datetime value under AlphaLinux.  (Note that
the link to submit a port-specific bug on your website is broken)

-Test Case:
----------
testdb=> create table dttest (dt datetime);
testdb=> insert into dttest values ('now');

--------------------------------------------------------------------------


Solution:
---------
The basic problem is the typedefs of AbsoluteTime and RelativeTime,
which are both 'int32'.  These types appear to be used synonymously
with the 'time_t' type, which on AlphaLinux is typedef'd as a 'long
int', which is 64-bits (not 32).  The solution included here fixes
the datetime type (it now passes the regression test), but does not
pass the absolute and relative time regression tests.  Presumably, a
more thorough investigation of how these types are used is warranted.
The included patch is from the v6.3.2 source, but can be applied to
the v6.4.2 source.  Please note that there is also a RedHat-specific
patch distributed with the PostgreSQL source package from RedHat
that was applied first.

aba8c12f67 We have tested the patches on three platforms:
NetBSD/macppc
LinuxPPC
FreeBSD 2.2.6-RELEASE

All of them seem happy with the regression test. Note that, however,
compiling with optimization enabled on NetBSD/macppc causes an initdb
failure (other two platforms are ok). After checking the asm code, we
are suspecting that might be a compiler(egcs) bug.

731603a92b A few further tweaks to shared memory space estimation.
This change brings the default size of the main shmem block back under 1MB,
which is a fairly popular value for the kernel's SHMMAX parameter.

02fa3e4394 Thank you for the advice. I concluded that current inet code has a
portability problem. Included patches should be applied to both
current and 6.4 tree. I have tested on LinuxPPC, FreeBSD and Solaris
2.6. Now the inet regression tests on these platforms are all happy.

bcfdc9df04 Repair some pretty serious problems in dynahash.c and
shared memory space allocation.  It's a wonder we have not seen bug
reports traceable to this area ... it's quite clear that the routine
dir_realloc() has never worked correctly, for example.

Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef
NOT_USED" for current. I have tested these patches in that the
postgres binaries are identical.

e77b630cf0 Allow maximum number of backends to be set at configure time
(--with-maxbackends).  Add a postmaster switch (-N backends) that allows
the limit to be reduced at postmaster start time.  (You can't increase it,
sorry to say, because there are still some fixed-size arrays.)
Grab the number of semaphores indicated by min(MAXBACKENDS, -N) at
postmaster startup, so that this particular form of bogus configuration
is exposed immediately rather than under heavy load.

724119a979 Modify int8 to not depend on sscanf(), and fix configure's test
for int8 support.  configure now checks only snprintf() for int8 support,
not sprintf and sscanf as it used to.  The reason for doing this is that
if we are supplying our own snprintf code (which does handle long long int),
we now only need working long long support in the compiler not in the
platform's C library.  I have verified that int8 now passes regression test
on HPUX 9, and I think it should work on SunOS 4.1.* and other older
platforms if gcc is used.

a7ad43cd18 Included patches make some enhancements to the multi-byte support.
o allow to use Big5 (a Chinese encoding used in Taiwan) as a client
  encoding. In this case the server side encoding should be EUC_TW

o add EUC_TW and Big5 test cases to the regression and the mb test
  (contributed by Jonah Kuo)

o fix mistake in include/mb/pg_wchar.h. An encoding id for EUC_TW was
  not correct (was 3 and now is 4)

o update documents (doc/README.mb and README.mb.jp)

o update psql helpfile (bin/psql/psqlHelp.h)

157349e3af Improper addition of NaN/Infinity recognition to float8in()
was causing it not to detect out-of-range float values, as evidenced by
failure of float8 regression test.  I corrected that logic and also
modified expected float8 results to account for new error message
generated for out-of-range inputs.

3b3ffc8d97 From: Magnus Hagander <mha@sollentuna.net>
Here is a first patch to cleanup the backend side of libpq.
This patch removes all external dependencies on the "Pfin" and "Pfout" that
are declared in pqcomm.h. These variables are also changed to "static" to
make sure.
Almost all the change is in the handler of the "copy" command - most other
areas of the backend already used the correct functions.
This change will make the way for cleanup of the internal stuff there - now
that all the functions accessing the file descriptors are confined to a
single directory.

6d5d673ca8 Be more careful to check input string lengths as well as values
when deciding whether a field is a year field.  Assume *anything* longer
 than 2 digits (if it isn't a special-case doy) is a valid year.
 This should fix the "Y1K" and "Y10K" problems
  pointed out by Massimo recently.
Check usage of BC to require a positive-valued year; before just used it
 to flip the sign of the year without checking. This led to problems
 near year zero.
Allow a 5 digit "concatenated date" of 2 digit year plus day of year.
Do 2->4 digit year correction for 6 and 5 digit "concatenated dates".
 Somehow forgot this originally. Guess not many folks use it...

c715788681 Handle "NaN" and "Infinity" for input values.
I think NAN is already guaranteed to be there from Jan's work on NUMERIC,
 but perhaps HUGE_VAL needs some #ifndef's in the same place.
Should also include "-Infinity" as -HUGE_VAL sometime; not there yet.
